This is a hand edited patch and won't apply. Additionally, you need

After installing this dw1703 dkms package, you have to add one more file under /etc/modprobe.d/
cat dw1703.conf
   install ath3k modprobe btusb; modprobe --ignore-install ath3k;

I don't think the kernel team has committed to doing this yet, and they should be the ones adding the rls-p-tracking tag. rls-mgr-p-tracking tag is the appropriate one to use to get it considered.

I submitted the patch yesterday, but the maintainer didn't accept the way to enable the device.
To enable this device correctly, user have to load the btusb module before ath3k, so user need this line in his /etc/modprobe.d/ath3k.conf
    install ath3k modprobe btusb; modprobe --ignore-install ath3k;
And now, we have no way to order the module loading sequence in the kernel.

Maybe we should consider another way to enable this device.

AceLan Kao (acelankao) wrote :

I just verified that, on 3.0 kernel, the btusb will be loaded after ath3k.
But, on 3.2 kernel, btusb will be loaded before ath3k, so there is no loading order issue on 3.2 kernel.
I'll resend the patch again.

@Tim, can you confirm with AceLan that this was the original bug? It sounds like the BT is working to some extent, but maybe there is some other bug there?

Replying to comment #11, if the "GUI tool" issue still exist in Quantal, a new bug should be filed. This bug is for the device support on the hardware level.
